I've seen that too, border collies that are 27 at the shoulder and 'purebred'. But oddly came from a breeder that had 100+ dogs on the property including livestock dogs and some other assorted ones....

I know here in Alberta there's a lot of males that get to be around 50 or so, they're just made bigger here. Kilt gets called a sheltie mix all the time because she's small. Oh and Merle and most experts I run into agree that border collies only come in black and white. Uh huh.

That's why almost every black and white dog with a longer snout is called a BD mix in our shelters.

P.S. My question was "What color is a brown dog?" Apparently, "I don't know, but I know it's not a Border Collie." is not the correct answer. :P

I've definitely known purebred BC who were big enough that, if they were allowed to be as heavy as that dog appears to be from the picture, would probably weigh at least 75 lbs. There is a young agility dog in the area who is the tallest BC I've ever seen. He looks like a pony.
